Nyx was a primordial deity in Greek mythology that preceded the Titans and the Olympians, and was the personification of the night. She was the daughter of Chaos, out of which all creation originated, and the sister of Erebus, Gaea and Tartarus. She was married to Erebus and had a number of children, including Nemesis (retribution), Hypnos (sleep), Thanatos (death), Geras (old age), Eris (strife) and Charon (the boatman who brought the souls of the dead to the gates of the underworld). According to Hesiod, Nyx's home was in Tartarus, along with her children Hypnos and Thanatos.
